1.30(2) + X = 6.10
This would be one of a few equations to do. 1.30(2) represents the cartons of eggs which are each 1.30. the X will represent the price of pancake mix and the total is 6.10.
Answer:
1) solution is y = -7
2.) DNE
3.) Solution is y = -2
Step-by-step explanation:
1.) 2+3 = y + 12
Add the LHS and make y the subject of formula
5 = y + 12
Y = 5 - 12
Y = - 7
The solution of the equation is - 7
2.) 2 + 13 = 1 +8
Since there is no unknown variable and the sum of the numbers in the left hand side ( LHS ) is not equal to the sum of the numbers in the right hand side ( RHS ), it will be concluded that there is no solution in the equation.
3.) y - 7 = 2 - 11
Sum the RHS and make y the subject of formula
Y - 7 = -9
Y = -9 + 7
Y = -2
The solution of the equation is -2
Answer:
a) 
b) 
Step-by-step explanation:
Polar coordinates are represented as:
, where 'r' is the length (or magnitude) of the line, and '
' is the angle measured from the positive x-axis.
in our case:

to covert the polar to cartesian:


we can plug in our values:


the Cartesian coordinates are:


(b) to convert (x,y) = (6.06,-3.5)
we'll use the pythagoras theorem to find 'r'



the angle can be found by:




to convert radians to degrees:

writing in polar coordinates:

Answer:
The speed of car in miles per minute is
miles per minute and
The speed of car in mile per hour is 40 miles per hour,
Step-by-step explanation:
Given as :
The distance cover by car = 2
=
miles
The Time taken by car to cover distance = 3
min =
min
The speed o car in miles per minute = S miles/min
So, Speed = 
Or, S =
mie per min
∴ S =
miles per minute
Now, Let The speed of car in miles per hour = x miles/h
So, Time in hour =
×
=
hours
So , Speed = 
Or, x =
miles per hours
Or, x = 40 miles per hours
Hence The speed of car in miles per minute is
miles per minute and the speed of car in mile per hour is 40 miles per hour, answer
